Application filed June so, 1915. Serial m. 37,235.

of Alabama, have invented anew and useful Churn; and I do hereby declare the followmg to be a fulhclear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved churn, and one ofthe features of the invention is to provide a pair of churning elements in combination with a mechanism for imparting revcluble movements in opposite directions to the churning elements, said mechanism being raisable to disconnect the same from the element, whereby the elements and the churn receptacle may be removed.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawingsz Figure 1 is a View partly in elevation and partly in section of the churn constructed in accordance with the invention. Fig. 2 is a sectional View through the gear mechanism. Fig. 3 is a view in elevation of the gear mechanism at right angles to that shown in Fig. 1. Fig. 4 is a sectional view on line eti of Fig. 1. Fig. 5 is a view showing another form of gear mechanism.

Referring to the drawings, 1 designates the churn receptacle and 2denctes the closure or cover therefor, which is rabbeted at 3 annularly to lit the shoulder 4 of the flanged opening 5 of the receptacle. The shanks or stems 6 of the churning elements 7 pass through openings 8 of the cover or closure. The collars 9 are secured on the shanks or stems 6 by means of set screws 10 to hold the lower-ends of the churning elements for contactingfrictionally with the bottom of the receptacle 1. The receptacle 1 engages within the flange 11 of thebase 12,130 prevent movement of the receptacle laterally.

Bolted at 13 to a vertical support 14:, which may be either a wall orstandard is a plate 15 having a vertical portion 16, which is T-shaped incross section. This T-shaped portion has a dove-tailed guide 17, into Specification of Letters Patent.

Patented Jan. 25,1316.

I which the vertical part v18 of the bracket 19 isdoye-tailed, and which bracket,whe'n in its lowermost positlon and the churningelenents are in operativepositions, rests upon the shoulder. 19*, at the bottom of the dovetailed guide 17; When the bracket 19 is in such position as shown in Figs. 1 and 2, the set screw 20 (which is threaded through one of the walls of the clove-tailed guide 17,), holds the bracket against being raised.

Journaled upon a lateral pin 21 of the bracket is a disk 22 having double gear portions23 and 2e meshing with the gears 25 and 26 of the shafts 27 and 28.

A crank 29 is loosely mounted upon the reduced part 30 of thelateral pin 21 and has a projection 31 engaging a recess 32 of the disk 22,so that by turning the crank motion is imparted to the disk 22. A nut 33 holds the crank on said reduced portion.

rectangular sockets 34 and 35.to IQCGLVO correspondingly shaped parts 36 of the shank or stem 6 of the churning element 7.

it will be seen that by loosening the set screw 20, the bracket 19 (in the lateral portion 38 of which. the shafts 27 and 28 are journaled) may be raised, thereby disengaging the sockets from the rectangular parts 36, so that the receptacle 1 and the churning elements therein may be easily removed after churning.

In Fig. 5the bracket 89 corresponding to the bracket 19 is not adjustable, but is secured at 40 to the stationary vertical sup.- port 14. In this case, the shanks or stems 6 of the churning elements may be detached from the shafts 27 and 28 by removing the pins 41, and lowering the churning elements.

The purpose in making the bracket adjustable as well as the collars 9, is to enable containers with thicker bottoms to be used. Furthermore, the purpose of making the collars adjustable is to permit taller containers to be used. adjustable, as well as the collars is to permit the churning elements to be adjusted adjacent the top of the container.

The invention having been set forth, what is claimed as new and useful is v In combination, achurn receptacle, a pair of churning elements operable in said receptacle and having shanks penetrating through and revoluble in the top of the receptacle a r no.1,

Also by making the bracket and. terminating at their upper extremities in squared ends, a pair of revoluble members alined axially with the upper end of said shanks and having squared sockets to receive said squared ends, means for operating said revoluble members, and a pair of collars, one adjustable upon each shank, said collars having set screws to hold-the collars in adjusted positions on the shanks, and which collars constitute means to engage the top of the receptacle as the shanks rotate, to support the churning elements as they rotate inraised or lowered positions, said collars J.
